Answer:

Evolution Genetics

Explanation:

Genetic evolution of living beings is the process of the disappearance or emergence of new species due to genetic variability. This process is very slow and can take up to thousands of years so it is difficult to keep up with the evolution process.

The research shown in the question above is an example of genetic evolution research. This is because antibiotics are substances that have the power to kill any kind of bacteria, however some bacteria evolve, new species of bacteria have emerged that have the ability to resist and survive the action of antibiotics.

Answer:

agouti - aaBbCc

solid color - AaBBCC

agouti black - AAbbCc

albino - AaBbcc/Aabbcc/AABBcc

Explanation: All the phenotypes that contain cc will be albinos, so they won't present any pigment deposition. Agouti black depends on the A gene to be homozygous and the B to be recessive, so the phenotype AAbbC_ is the correspondent. If A is not homozygous and B isn't recessive, we have agouti color. If B is homozygous and A recessive, we have a solid color.

Answer: Option D.

Genotype by environment interaction.

Explanation:

Genotype by environment interaction refer to a situation where two different genotypes react differently in an environment. Light skinned humans are at greater risk of skin cancer because they lack melanin which the dark people have and this melanin protect the skin from sun.

All the choices are correct. Differences in the norm of reaction I.e they react different way.

Epistasis is when the effect of a gene suppress the other.

Pleiotrophy is when a gene influence another genes phenotipically. These are all genotype enviromr interaction.
